Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical auxiliary breathing equipment, in particular to a respiratory nursing auxiliary breathing device for patients in the respiratory department. Background Art
[0002] In modern clinical medicine, ventilators, as key devices that artificially replace spontaneous ventilation, have been widely used in the treatment of respiratory failure, perioperative respiratory support, and critical care resuscitation, becoming an indispensable component of modern medicine. During the clinical application of ventilators, the mask, as a core component of human-machine interaction, has a direct impact on treatment efficacy and patient compliance due to its adaptability and pressure regulation capabilities.
[0003] Traditional masks rely on a mechanical headband fastening mechanism, requiring the patient or caregiver to manually adjust the tightness. Critically ill patients (such as those who rely on mechanical ventilation) and patients with limited upper limb mobility (such as those with spinal cord injury) are unable to complete fine adjustments independently, and are prone to pressure sores on the bridge of the nose due to uneven pressure distribution. Clinical monitoring data show that when the patient changes position (such as from supine to lateral position), the contact pressure of the traditional mask can fluctuate by up to ±40% of the initial setting value; and the existing device lacks a pressure compensation mechanism and cannot effectively respond to the instantaneous pressure surge caused by rapid changes in facial expressions (such as coughing and sneezing). Summary of the Invention
[0004] Based on this, it is necessary to provide a respiratory nursing device to assist patients in breathing, in order to address the problems that uneven pressure distribution of the mask can easily lead to the formation of pressure sores on the bridge of the nose and the inability to effectively respond to the instantaneous pressure surge caused by rapid changes in facial expressions.

[0006] A ventilator and a controller, wherein the controller is provided on the ventilator;
[0007] A face mask, wherein a connecting tube is provided between the face mask and the respirator;
[0008] A self-adaptive adjustment mechanism, the self-adaptive adjustment mechanism further comprising an elastic band in contact with the patient's head and an adjustment assembly for achieving connection between the mask and the elastic band;
[0009] There are two elastic bands, and one elastic band is used with two adjustment components. A plurality of flexible film pressure sensors are embedded in the inner side of the elastic band close to the patient.
[0010] The flexible film pressure sensor includes a polyvinylidene fluoride piezoelectric film bottom layer, a middle flexible polyimide substrate, and a silica gel protective layer. The polyvinylidene fluoride piezoelectric film bottom layer and the middle flexible polyimide substrate are both embedded in the elastic band. One side of the silica gel protective layer contacts the middle flexible polyimide substrate, and the other side contacts the patient's face when the device is in use.
[0011] The adjustment component further includes a connection seat, a placement box, an adjustment block, and a micro double-headed motor provided on the face mask. The micro double-headed motor is installed in the placement box. A roller is rotatably connected in the placement box. The end of the elastic band is wound around the surface of the roller. Active gears are fixedly connected to both ends of the micro double-headed motor. Driven gears meshing with the active gears are fixedly connected to both ends of the roller. A connection buckle is provided on the side of the adjustment block away from the placement box. A micro electric push rod is provided in the adjustment block. The telescopic end of the micro electric push rod penetrates through the adjustment block and is fixedly connected to the placement box.
[0012] In one embodiment, the adjustment component further includes a rotating rod. A first circular groove is opened inside the connection seat. A guiding port communicating with the first circular groove is opened on the inner side of the connection seat. A second circular groove is opened in the connection buckle. The end of the rotating rod sequentially penetrates through the connection buckle, the second circular groove, and the guiding port and is fixedly connected with a clamping block. The clamping block is located in the first circular groove. A coil spring is provided between the rotating rod and the inner wall of the second circular groove.
[0013] In one embodiment, a contact pad is provided on the side of the face mask close to the patient's face. The contact pad is a component made of medical soft silica gel material.
[0014] In one embodiment, a plurality of pressure sensors are embedded in the contact pad. The output end of the pressure sensor is signal-connected to the input end of the controller.
[0015] In one embodiment, an indicator light is provided on the outer surface of the face mask. The input end of the indicator light is signal-connected to the input end of the controller.
[0016] In one embodiment, a telescopic rod is provided in the adjustment block. One end of the telescopic rod is fixedly connected to the placement box.
[0017] In one embodiment, support seats are provided at the four corners of the bottom of the ventilator. A contact layer is provided at the bottom end of the support seat. The contact layer is a component made of rubber material. A handle is provided at the top end of the ventilator.
[0018] In one embodiment, a connection valve is provided on one side of the ventilator. The connection valve is connected to one end of a connecting pipe.
[0019] In one embodiment, the other end of the connecting pipe is provided with a connector, and one end of the connector away from the connecting pipe is inserted into the face mask.
[0020] In one embodiment, a pressure regulating valve is provided on the surface of the connecting pipe.
[0021] In the above device, the self-adaptive adjustment mechanism can ensure the connection stability between the face mask and the patient's face. The flexible film pressure sensors are arranged in an array, and the measurement of the pressure value is relatively accurate. The adjustment component adjusts according to the values of the flexible film pressure sensors in the corresponding area. During the adjustment process, there is no need for the patient or medical staff to manually operate, avoiding the inaccuracy of manual adjustment and the problem of touching the patient's head during adjustment, ensuring the treatment effect and patient compliance. Moreover, the micro electric push rod can adjust the distance between the placement box and the adjustment block, avoiding the situation of local tightness when only adjusting the elastic band, increasing the applicable range of the device and also increasing the adjustment range of the device, and can perform automatic adaptation when the patient has facial expression changes or turns over.
[0022] Under the mutual cooperation of the rotating rod, the clamping block and the first circular groove in the adjustment component, the disassembly of the connecting seat and the connecting buckle can be quickly completed. During the disassembly process, there is no need to lift the patient's head, reducing the impact on the patient, quickly completing the detachment of the face mask from the patient's face, and reducing the discomfort when removing the face mask.

[0039] The following Figures 1-8 describes a respiratory care auxiliary patient breathing device of the present invention.
[0040] In one embodiment, a respiratory care auxiliary patient breathing device includes:
[0041] A ventilator 100 and a controller 500, the controller 500 is provided on the ventilator 100;

[0044] There are two elastic bands 410, and one elastic band 410 is used in combination with two adjustment components 430. A plurality of flexible film pressure sensors 420 are embedded on the inner side of the elastic band 410 close to the patient;
[0045] The flexible film pressure sensor 420 includes a polyvinylidene fluoride piezoelectric film bottom layer, a middle flexible polyimide substrate, and a silica gel protective layer. The polyvinylidene fluoride piezoelectric film bottom layer and the middle flexible polyimide substrate are both embedded in the elastic band 410.

[0046] The adjusting assembly 430 further includes a connecting seat 436, a placement box 431, an adjusting block, and a micro double-headed motor 433 provided on the mask 200. The micro double-headed motor 433 is installed in the placement box 431. A roller 432 is rotatably connected in the placement box 431. The end of the elastic band 410 is wound around the surface of the roller 432. Active gears 434 are fixedly connected to both ends of the micro double-headed motor 433.

A connecting buckle 437 is provided on the side of the adjusting block away from the placement box 431. A micro electric push rod 439 is provided in the adjusting block. The telescopic end of the micro electric push rod 439 penetrates through the adjusting block and is fixedly connected to the placement box 431.
[0047] It should be noted that the main components of the ventilator 100: The gas source system compresses gas (oxygen and air): provides the basis for gas mixing, usually supplied through a central gas supply system or high-pressure gas cylinders.
[0048] The mixing valve (air-oxygen mixer): adjusts the oxygen concentration FiO2 to ensure that the oxygen concentration of the gas inhaled by the patient meets the set value, such as 21% - 100%.

[0055] The humidifier: warms and humidifies the inhaled gas to prevent airway dryness. Some devices integrate a heated wire pipeline.
[0056] Filter: Prevent bacteria or particles from entering the patient's airway or contaminating the device.
[0057] Alarm system
[0058] Monitor abnormal conditions such as high / low pressure, asphyxia, oxygen concentration deviation, power failure, etc., and trigger audible and visual alarms;
[0059] Moreover, in the prior art of the ventilator 100, the machinery well-known to those skilled in the art, therefore, no label description is given to it.
[0060] The data collected by the flexible film pressure sensor 420 and the pressure sensor 220 will be transmitted into the controller 500. At the same time, the controller 500 can control the operation of the micro double-headed motor 433 and the micro electric push rod 439 according to the collected data, so as to achieve the adaptive pressure of the face mask 200 on the patient's face.
[0061] Such as Figure 1 and Figure 4 As shown, a contact pad 210 is provided on the side of the face mask 200 close to the patient's face, and the contact pad 210 is a component made of medical soft silicone material.
[0062] A plurality of pressure sensors 220 are embedded in the contact pad 210, and the output end of the pressure sensor 220 is signal-connected to the input end of the controller 500.
[0063] An indicator light 230 is provided on the outer surface of the face mask 200, and the input end of the indicator light 230 is signal-connected to the input end of the controller 500. The indicator light 230 can adopt a relatively common alarm light on the market, and can be distinguished by red and green lights, representing different states.
[0064] In this embodiment, after the face mask 200 is attached to the patient's face, the contact pad 210 will directly contact the skin, increasing the comfort of wearing the face mask 200, and its contact pressure can be transmitted to the pressure sensor 220. The pressure sensor 220 will transmit the signal to the controller 500. When the pressure value is within a reasonable range, the indicator light 230 will be green, and when it exceeds the range, it will be red. Moreover, during the initial wearing process, it can also be determined whether the wearing is reasonable.
[0065] Such as Figure 3 、 Figure 5 、 Figure 7 and Figure 8As shown, the adjusting component 430 further includes a rotating rod 438. A first circular groove 4362 is formed inside the connecting seat 436, and a guiding port 4361 communicating with the first circular groove 4362 is formed on the inner side of the connecting seat 436. A second circular groove 4371 is formed inside the connecting buckle 437. The end of the rotating rod 438 sequentially passes through the connecting buckle 437, the second circular groove 4371, the guiding port 4361 and is fixedly connected with a clamping block 4382. The clamping block 4382 is located inside the first circular groove 4362. A coil spring 4381 is arranged between the rotating rod 438 and the inner wall of the second circular groove 4371.
[0066] In this embodiment, when it is necessary to urgently disassemble the face mask 200, operate the rotating rod 438, apply an outward force to the rotating rod 438 while accompanied by a rotating action. When the clamping block 4382 coincides with the guiding port 4361, the rotating rod 438 and the connecting buckle 437 are pulled out, realizing the separation of the connecting buckle 437 and the connecting seat 436, and sequentially completing the disassembly of the corresponding area, removing the face mask 200 from the patient's face. During the disassembly process, there is no need to lift the patient's head, reducing the impact on the patient, being able to quickly complete the detachment of the face mask 200 from the patient's face, and reducing the discomfort when removing the face mask 200.
[0067] As Figure 1 、 Figure 2 、 Figure 7 and Figure 8 shown, a telescopic rod is arranged inside the adjusting block, and one end of the telescopic rod is fixedly connected with the placement box 431. When the adjusting block and the placement box 431 need to be adjusted, the telescopic rod can limit their positions to avoid deviation during adjustment. The above-mentioned telescopic rod is a common existing component, and as can be clearly seen in the appendix Figure 7 it is two connecting rods inserted into each other. One end of one connecting rod is fixedly connected with the adjusting block, and one end of the other connecting rod is fixedly connected with the placement box 431, so as to achieve the purpose of limiting the position.
[0068] Support seats 120 are arranged at the four corners of the bottom of the ventilator 100. A contact layer is arranged at the bottom end of the support seat 120, and the contact layer is a rubber material component. A handle is arranged at the top end of the ventilator 100. The support seat 120 can increase the stability of the device during use, and the handle is convenient for transferring the device.
[0069] A connection valve 110 is arranged on one side of the ventilator 100, and the connection valve 110 is connected with one end of the connection pipe 300.
[0070] The other end of the connection pipe 300 is provided with a connection head 320, and the end of the connection head 320 away from the connection pipe 300 is inserted into the face mask 200.
[0071] A pressure regulating valve 310 is arranged on the surface of the connection pipe 300.
[0072] In this embodiment, when a patient in the nursing department needs to use a breathing device, the ventilator 100 can be placed beside the hospital bed, and the power cord can be connected. After setting the basic settings of the ventilator 100, medical staff use the self-adaptive adjustment mechanism 400 to wear the face mask 200 on the patient's face. After the connection is completed, the ventilator 100 can be used to assist the patient in breathing;
[0073] When there is a non-conformity between the patient's face and the face mask 200 or excessive local pressure, the flexible film pressure sensor 420 will transmit a signal to the controller 500. The micro double-headed motor 433 will drive the driving gear 434 to rotate. Under the meshing action of the driven gear 435, the roller 432 will drive the elastic band 410 to rotate, so as to complete the adjustment of the local pressure by using the adjustment component 430, so that the elastic band 410 is within a reasonable pressure range. The adjustment of the four parts is carried out according to the pressing values of the flexible film pressure sensors 420 in the corresponding areas. If the pressure in the area is too high, it will be loosened; if the pressure value is small, the elastic band 410 in this area needs to be wound up to ensure the stability of the face mask 200 wearing and the comfort of the patient;
[0074] If the patient has an emergency and needs to exceed the limit, operate the rotating rod 438, while applying an outward force to the rotating rod 438 and accompanied by a rotating action. When the latch 4382 coincides with the guiding port 4361, the rotating rod 438 and the connecting buckle 437 are pulled out, realizing the separation of the connecting buckle 437 and the connecting seat 436. During emergency disassembly, there is no need to move the patient's head, which will not affect the patient.
[0075] It should be noted that in the above description, the ventilator 100, the connection valve 110, the face mask 200, the pressure sensor 220, the indicator light 230, the pressure regulating valve 310, the flexible film pressure sensor 420, the micro double-headed motor 433, the micro electric push rod 439, the controller 500, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the ventilator 100, the pressure sensor 220, the indicator light 230, the pressure regulating valve 310, the flexible film pressure sensor 420, the micro double-headed motor 433, the micro electric push rod 439, and the controller 500 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0076] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0077] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
